Beyond the irony of a man shooting himself during a class that was ostensibly intended to teach him about gun safety,
this incident highlights the dangers inherent in a society where people
routinely carry firearms. Guns are dangerous machines which can
accidentally discharge, threatening the gun owner or innocent
bystanders.

If Nebraska’s law is anything like Wisconsin’s, this guy will get his
permit eventually, despite proving pretty much conclusively that he’s a
menace — that is, assuming he’s dumb enough to still want it. These
classes are pretty much just formalities and, as a result, jokes.
Remember, safety is not the purpose behind these sort of gun/paranoia
laws. The purpose is to sell more guns. And you’re not going to get more
guns out on the street if people like Quick Draw McGraw here get
flunked out of these certification classes. If he wants, he can try
again — and again and again and again. It’s the same principle behind
opposition to background checks — if someone gets flagged on the check,
there’s no sale.

That whole thing about being worried about “federal gun registries”
is just propaganda for the weakminded and gullible. Being against
background checks is about being able to sell guns to criminals. Period.
Just like “concealed carry classes” are just a way to sell them to
paranoid clowns.
